Neeg xa xov liaison RNA ( mRNA ) yog RNA uas nqa cov ntaub ntawv los ntawm DNA mus rau ribosome, qhov chaw ntawm cov protein synthesis (txhais lus) hauv cell. Lub coding sequence ntawm lub mRNA txiav txim siab cov amino acid ib ntus hauv cov protein uas tsim tawm.
Ib yam li ntawd ib tug yuav nug, hom RNA nqa cov ntaub ntawv uas qhia txog cov lus nug protein?
Cov txheej txheem uas cov hlwb siv cov cov ntaub ntawv ntawm RNA ua cov proteins hu ua transcription. Tsuas muaj ob lub ntsiab hom RNA xav tau los ua cov proteins , tRNA thiab rRNA. Cov hom RNA uas xa cov amino acids rau lub ribosome thaum lub sij hawm protein ntau synthesis yog tRNA.
Tsis tas li ntawd, hom RNA twg nqa cov amino acids rau ribosome? hloov RNA (tRNA
Kuj tseem paub, txhua hom RNA tseem ceeb npaum li cas rau kev tsim cov protein?
Ribosomal RNA (rRNA) koom nrog ib pawg ntawm cov proteins rau daim ntawv cov ribosomes. Cov txheej txheem nyuaj no, uas lub cev txav mus raws ib qho mRNA molecule, catalyze lub sib dhos ntawm cov amino acids rau hauv protein ntau chains. Lawv kuj khi tRNAs thiab ntau yam khoom siv molecules tsim nyog rau protein synthesis.
Hom RNA twg yog siv los ua tus qauv rau kev txhais cov proteins?
Neeg xa xov liaison RNA (mRNA)

Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Cov yam ntxwv ntawm cov ntaub ntawv twg yog qhov ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis heev?
Variation: Ib qho kev ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis sib txawv. ? Kev faib tawm: Cov xwm txheej lossis cov duab ntawm kev sib kis ntawm cov ntaub ntawv hla ntau qhov tseem ceeb (xws li tswb-puab). ? Outliers: Cov qauv piv txwv uas nyob deb heev ntawm feem ntau ntawm lwm cov qauv nqi
Thaum muab piv cov qauv sau rau ib tus neeg raug liam cov ntaub ntawv lub hnub nyoog sib txawv ntawm cov ntaub ntawv yuav tsum tsis pub tshaj kaum ob lub hlis?
Thaum piv cov qauv sau rau tus neeg raug liam? cov ntaub ntawv, lub hnub nyoog sib txawv ntawm cov ntaub ntawv yuav tsum tsis pub ntau tshaj rau rau kaum ob lub hlis. Tus lej txaus ntawm tus qauv yog qhov tseem ceeb rau kev txiav txim siab qhov tshwm sim ntawm kev sib piv
Dab tsi yog cov cuab yeej lossis cov ntaub ntawv uas tus Kws Tshawb Fawb xav tau los txheeb xyuas cov ntaub ntawv nug?
Cov ntaub ntawv raug nug hauv chav kuaj ua txhaum cai yog nruab nrog lub tshuab ntsuas ntsuas, ntsuas cov duab digital, infrared thiab ultraviolet lub teeb ci, cov cuab yeej tshuaj ntsuam video thiab cov cuab yeej tshwj xeeb suav nrog cov khoom siv hluav taws xob tshawb pom electrostatic (EDD) thiab cov khoom siv los ua chemistry
Dab tsi yog cov kab ke uas nqa cov ntaub ntawv caj ces ntawm lub cev?
Qhov sib lawv liag ntawm DNA nqa cov ntaub ntawv caj ces ntawm lub cev. Cov txheej txheem ntawm DNA replication tsim ib daim qauv tshiab ntawm cov kab mob cov ntaub ntawv caj ces. Cov duab ob-coiled ntawm DNA yog hu ua ob chav helix. Proteins yog tsim los ntawm cov amino acids
